hello everyone, I own a civic hybrid from 2010, I want to know if anyone has an idea about my problem, it started 2 or 3 years ago, IMA default which turns on then turns off, I am aware that you must not leave the car without driving, this car I bought used witha battery ima changed under warranty the famous years 2009 and 2010, well until the last few months when I had anomalies engine battery,drive indicator ,lights ima of course, I took the car to honda and before arriving everything went restarted only the ima indicator light remained onthe diagnosis was obviously low battery ima: price 2800 $, well I took the option of trying a grid charger, so I recharge my battery it works pretty much but everything starts again the 4 LEDs that light up, I hardly change the battery, unfortunately after 20 miles again the 4 leds, discussion with honda but their diagnostic tool shows no communication between the command module ima code U0110, U1205, they are unable to determine what is the origin of the problem,you have to change the BCM yes but $ 2500, I tell them stop, I take the car back and I will try to change the components BCM, MCM PCM inverter used, I do not trust honda. I am expecting some pieces from UK , and USA, any ideas?

 

No ideas whatsoever. Without diagnostic trouble codes, it's just senseless guessing.

Step 1 is to confirm that your 12V battery is fully charged and healthy.

 

thank you for your interest in my problem, the fault codes may not be the same in the states as in France I send you the report, I have a new BCM but without change, I am waiting for an inverter convector, as I read it 've already said i don't trust honda they are fumbling, my 12v battery is new and charged at 13v,90000 miles,

last control

 

Connection issue, wiring issue (broken wire, chewed through), bad MCM and/or bad BCM. No indication it's the inverter or converter.

Get yourself a manual. The diagnostic steps for those codes are 6 pages and 39 steps.

 

not found in France very few vehicle of this type, and the mechanic does not give any explanations

 

check your messages.

let me give you some details on the startup timeline;
when I switch on the ignition I hear the relays on the back flapping, battery indicator light on, engine fault indicator light on, I turn the key and start with the electric motor assistance the battery indicator does not go out the anomaly the fan starts up the load bars go up but almost instantly we hear the fan struggling and stops everything turns on the relay clicks again.my hope is falling
f....g honda hybrid ,

 

hi,I tried to test step by step as in the manual however there are differences, the MCM 20 p connector is at 14p the wires are not really red or blue but multicolored,
for now the only certainty the relays are good, the BCM 40p connector several red wires:
MCM red wire nothing, BCM red 12v. Difficult to conclude anything effective, what do you think? some photos of the site.


BCM/MCM

CONNECTOR 14P AND NOT 20P

red wire

connector 40p 4 red wires

 

The Orange 14P connector is not relevant to the diagnostic for your codes.

Per the steps, the BCM must be removed. Unplug the 14P and 40P connectors. Remove the two nuts. Remove the BCM.

The 20P connector should be visible once BCM is removed.

Reminder - protect yourself from electric shock.
